NOZZLE FOR SAUSAGE-STUFFING MACHINES,

Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed April 23, 1910. Serial No. 557,253.

To all whom it may concern.'

Be it known that I, ERNEST C. GUNUSKEY, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inNozzles for Sausage-Stutling Machines, of which the following is aspecification.

My invention relates to nozzles for sausage stufling machines, and itsobject is to provide a nozzle which will permit a ready escape of airfrom the sausage casing. Unless provision is made for the escape of suchair it tends to accumulate in the casing as the meat is forced therein,and frequently results in bursting the casing.

IVith the above object in view, and to provide a nozzle which shall beeective in operation and comparatively cheap to manufact-ure, and whichmay be litted to various types of existing machines, my inventionconsists in the construction and arrange-v ment of parts hereinafterdescribed, claimed, and illustrated in the accompanying drawing, inWhich,

Figure 1 is a central longitudinal section through my improved nozzle,showing the clamping means employed to hold it in position; and, Fig. 2is a perspective view of the nozzle itself, the parts thereof beingseparated.

Referring to the drawings in detail, my improved nozzle comprises aninner tube 1 and an outer tube 2 which are preferably slightly taperingand which are concentrically arranged, as clearly shown in Fig. l. Theinner tube 1 is solid, while the outer tube 2 is provided almostthroughout its length with a series of perforations 3. The outer andinner tubes are provided at their inner ends with parallel annularflanges 4, and l5, respectively. These fianges are spaced apart by meansof spacing blocks G secured to one of the flanges, which blocks extendalso along the inner tube so as to space the tubes apart at the endadjacent the flanges. At the outer end, the tubes are spaced apart bymeans of flaring or expanding t-he end of the inner tube, as indicatedat 7 in Fig. 1.

The two tubes constituting the nozzle are adapted to be clamped inposition as shown in Fig. 1, by means of a clamping ring 8 which engagesthe flange 4, and which is itself provided with a cam flange adapted toengage under suitable lugs 9, carried by the head 10 of the sausagemachine cylinder. This head has a hollow projecting boss 11 againstwhich the flange 5 of the inner tube is pressed, so as to form a tightjoint.

The casing to be filled is slipped over the outer tube 2 in the wellknown manner, and the meat enters the casing through the inner tube 1.The air in the casing passes through the perforations 3 into the annularpassage 1Q between the tubes, thence through the passage 13 between theflanges, thence through the passages 14 and 15 formed between thecylinder head and the clamping ring, whence it escapes.

It will thus be seen that with my improved construction I have providedtight joints at all points past which the meat is forced, but at thesame time, I have formed an open air passage or channel through whichthe air in the casing may escape to the atmosphere, and it is thoughtthat the numerous advantages of my invention will be readily appreciatedby those skilled in the art.

What I claim is 1. A nozzle for sausage stufling machines comprising apair of concentrically arranged tubes spaced apart so as to preserve anair passage therebetween, and means for rigidly maintaining said tubesin such concentric, spaced relation.

2. A nozzle for sausage stuffing machines comprising an outer perforatedtube adapted to receive the sausage casing, and an inner imperforatetube concentric therewith, said tubes being spaced apart to form an airpassage therebetween, and means at. each end of said tubes forpreserving such spaced relation.

3. A nozzle for sausage stuliing machines comprising an outer perforatedtube over which the sausage casing is adapted to be slipped, and aninner imperforate tube through which the meat is fed, said tubes beingconcentrically arranged and provided at their inner ends with parallelannular flanges, such flanges being adapted to engage a clamping devicefor securing the nozzle in position, said tubes and said flanges beingspaced apart to provide an air passage therebetween.

1. A nozzle for sausage stuffing machines Comprising` an Outer tube overwhich the saul ing means to maintain the two tubes in consage easing isadapted to be slipped, and an centric spaced relation. i0 inner tubethrough which the meat is fed, In testimony whereofaiifix my signature,spacing means between the inner ends of said in presence of twoWitnesses. tubes, and the outer end of said inner tube ERNEST C.GUNUSKEY. being` slightly flared in such manner as to Witnesses: engagethe inner Wall of the outer tube, GERTRUDE P. MORRIS, such flared endeoperating with said spae- A. P. CLARK.
